1) Suppose you added 100 mL of water to your vinegar sample in the Erlenmeyer flask instead of 50 mL. Would the titration have required more, less or the same amount of NaOH for a complete reaction? Explain. 2)You used a 10.00 mL volumetric pipet to dispense the vinegar sample. Can you use a cylinder instead if it has the same precision?
